Adding attachment from PI level

[former_member209575]

Hi all,

I am trying to add some attachment to payload using JAVA Mapping.

*********************************************************************

public void transform(TransformationInput arg0, TransformationOutput arg1) throws StreamTransformationException

{

try{

System.out.println("JAVA Mapping is Initiated");

//getTrace().addInfo("JAVA Mapping HMAC is Initiated");

InputStream stream1 = arg0.getInputPayload().getInputStream();

String inputPayload = convertInputStreamToString(stream1);

System.out.println("input file "+inputPayload);

String outputPayload = "";

outputPayload = inputPayload;

byte[] b = inputPayload.getBytes();

System.out.println("JAVA Mapping "+b.length);

try{

*OutputAttachments outputAttachments = arg1.getOutputAttachments();

Attachment attachments = outputAttachments.create("sd", b); *

outputAttachments.setAttachment(attachments);

} catch (Exception e)

{//getTrace().addInfo("JAVA Mapping Trace "+e);

System.out.println("test "+e);}

arg1.getOutputPayload().getOutputStream().write(outputPayload.getBytes("UTF-8"));

} catch (Exception e)

{System.out.println(e.getStackTrace());}

}

**********************************************************************************************************

I am getting null pointer exception from below line

*Attachment attachments = outputAttachments.create("sd", b); *

feels like

outputAttachments = arg1.getOutputAttachments(); is returning null.

Please help me in solving same

Regards

Have you checked "read attachments" in operation mappings?

Hi Stefan,

I tried with read attachment option also.

Here message is coming from R3 system as payload. I need to take some 5 fields and put it as attachment along with payload and need to send to other PI system.

Have you tried working with the addAttachment() method of the Message interface (http://help.sap.com/javadocs/pi/SP3/xpi/com/sap/engine/interfaces/messaging/api/Message.html#addAttachment%28com.sap.engine.interfaces.messaging.api.Payload%29) ... It may require some (major) redesign of your JAVA mapping (I'm still on XI, so I can't validate this assumption)
